Description

Technical Field

[0001] The present application relates to the technical field of bedding products, and in particular to a borderless pillow core. Background Art

[0002] In the rapidly developing modern home furnishing industry, the demand for high-quality sleep has driven the continuous innovation of pillow core technology. The goose down pillow cores on the market are roughly divided into goose down pillows, goose down feather pillows, goose down fiber pillows, etc., which use one filler or 2 to 3 mixed fillers. Common problems are single fillers or concentrated filler characteristics that are not complementary. For example, a single filler causes the pillow core to have insufficient support and is easy to collapse. Non-complementary filler characteristics cause the pillow to not fit the human body curve, the neck is not supported, and the pillow shifts and causes stiff necks.

[0003] From the manufacturing process point of view, the pillow core is usually composed of the upper, middle and lower parts of the outer fabric, the upper and lower parts of the upper fabric and the lower fabric, which are sewn together. Among them, the common processes at the joints of the upper fabric include quilting and inlaying, which are used to increase the three-dimensional sense and quality of the pillow core. However, this process reduces the skin-friendliness of the pillow core and ignores the impact of the foreign body sensation when the user uses it. The edge of the pillow core is usually hard and has a strong foreign body sensation, which is also a common problem in the existing technology.

[0004] When sleeping on your back, your shoulders and neck are in contact with the edge of the pillow over a large area. When sleeping on your side, the contact between the shoulder skin and the edge of the pillow is more obvious. The hard edge may cause discomfort to the user, or even skin allergies. This discomfort not only affects the user's sleeping experience, but may also pose a potential threat to the user's skin health. It can be seen that the existing technology has obvious deficiencies in terms of material selection and filler combination, rationality of sewing technology, and edge comfort.

[0005] Therefore, the pillow core structure needs to be further improved so that the pillow core has better support and higher durability, and the edge of the pillow core is softer and more comfortable to reduce the foreign body sensation. Utility Model Content

[0042] In some embodiments, Figure 3 As shown, the portion of the first fabric 11 projected onto the surface of the comfort layer 2 is pleated to form a plurality of three-dimensional grids. In this embodiment, the size of the three-dimensional grid is controlled by the pleating process, so that the edge of the pillow core gradually transitions to the center, fits the neck curve, and avoids the problem of the edge (i.e., the traditional vertical high inlay) being too hard.

[0043] Furthermore, the pleating forms include double pleats, flower pleats, diamond pleats, twisted flowers, reverse pleats, etc.

[0044] In some embodiments, the first fabric 11 may not be processed by the pleating process.

[0045] In some embodiments, the portion of the first fabric 11 projected onto the surface of the comfort layer 2 includes a neck support area 15, a head rest area 14, and two side sleeping areas 13. The neck support area 15 and the head rest area 14 are arranged between the two side sleeping areas 13, and the area of ​​the three-dimensional grid of the neck support area 15 is greater than the area of ​​the three-dimensional grid of the head rest area 14 and the side sleeping area 13.

[0051] The first fabric 11 is connected to the inner layer 4 and wraps the surface and all sides of the comfort layer 2. The pillow core of this embodiment is an integrated borderless pillow core, and each side of the pillow core has no vertical height, which reduces the sewing process at the vertical height and is more comfortable and skin-friendly.

[0052] The first fabric 11 is a 100S Tencel polyester-cotton single-layer down-proof fabric. The portion of the first fabric 11 projected onto the surface of the comfort layer 2 is pleated to form a 4*6 three-dimensional grid partition, including two neck support areas 15 (4 grids), a head rest area 14 (4 grids) and two side sleeping areas 13 (8 grids for each of the left and right side sleeping areas 13). The head rest area 14 is located between the two neck support areas 15.

[0053] The comfort layer 2 is filled with natural, pollution-free 90% washable white goose down, which provides an ultra-fluffy and soft sleeping feeling. Specifically, the three-dimensional grid of the side sleeping area 13 is filled with 6g of white goose down, and the three-dimensional grid of the head nest area 14 and the neck support area 15 is filled with 4g of white goose down, making the comfort layer 2 low in the middle and high around, providing a 360° soft wrapping feeling for the head, reducing the user's anxiety before going to bed.

[0054] The combination of the multiple three-dimensional grids of the first fabric 11 of this embodiment and the filled white goose down can prevent the white goose down from shifting during use and make the white goose down evenly distributed and full.

[0055] The curved design of the neck support area 15 of this embodiment increases its contact area, reduces the friction coefficient between the neck and the pillow core during sleep, relieves the pressure on the neck muscles, and provides the user with a naked sleeping experience.

[0056] The support layer 3 of this embodiment is 50D non-temperature-sensitive memory foam. The combination of white goose down and memory foam in this embodiment improves the softness, support and breathability of the pillow core.

[0057] The support layer 3 of this embodiment is provided with a plurality of 5mm first vertical through holes 31 distributed in a circular shape when projected on the head socket area 14, and a plurality of 3mm second vertical through holes 32 distributed in a C shape when projected on the two side sleeping areas 13, so that the pillow core can accurately support the weight of the head when the user sleeps on his back, provide stable support, adapt to changes in sleeping posture, fit the facial curve of the user when sleeping on the side, and reduce the pressure on the ears when sleeping on the side.

[0058] In this embodiment, the inner layer 4 is a 100S Tencel polyester-cotton single-layer down-proof fabric.

[0059] Example 2

[0060] The difference between this embodiment and the first embodiment is that the portion of the first fabric 11 projected onto the surface of the comfort layer 2 is formed into a 6*6 three-dimensional grid partition by pleating.

[0061] The first fabric 11 is connected to the inner layer 4 and wraps the surface of the comfort layer 2 and the sides of the comfort layer 2 in two length directions, so that both length sides of the pillow core are edgeless structures.

[0062] One end of the second fabric 12 is connected to the inner layer 4, and the other end is connected to the first fabric 11, and wraps the two side edges in the width direction of the comfort layer 2 to form the height of the pillow core, so that the two width edges of the pillow core have the height of the embedded line.

[0063] The comfort layer 2 is filled with silk. The support layer 3 is latex.

[0064] Example 3

[0065] The difference between this embodiment and embodiment 1 is that the first fabric 11 is connected to the inner layer 4 and wraps the surface of the comfort layer 2 and the side edge of the comfort layer 2 in one length direction, so that one length side of the pillow core is a borderless structure.

[0066] One end of the second fabric 12 is connected to the inner layer 4, and the other end is connected to the first fabric 11, and wraps the two side edges in the width direction and the other side edge in the length direction of the comfort layer 2 to form the standing height of the pillow core, so that the three sides of the pillow core have the standing height of the inlay line.

[0067] The comfort layer 2 is filled with functional fibers, and the support layer 3 is silicone.

[0068] Example 4

[0069] The difference between this embodiment and the third embodiment is that the first fabric 11 is a woven fabric without pleats, the comfort layer 2 is made of silk or mulberry silk, and the support layer 3 is made of any material selected from memory foam, silica gel and latex.

[0070] In some embodiments, the borderless pillow core of this embodiment can solve the foreign body sensation caused by the vertical high sewing process of the traditional pillow core, and improve the fit between the pillow core and the user's shoulder and neck; it can improve the pillow collapse, insufficient support, non-fitting human body curve, foreign body sensation in the neck, pillow displacement and stiff neck caused by the single filling of traditional goose down pillows, goose down feather pillows, goose down fiber pillows, or the non-complementary characteristics of concentrated fillings. The borderless pillow core of this embodiment enriches the sleeping feeling of molded and foamed pillow cores such as memory foam, latex, and silicone. The comfort layer 2 uses materials such as silk to provide skin-friendly touch, and uses its concave arc shape to create a sense of wrapping and sinking, providing users with a comfortable pre-sleep environment and an effectively supported post-sleep experience, reducing problems such as shoulder and neck pain and stiff neck when waking up, and improving insomnia.

[0071] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by a person with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
